Connecting measurement modules
The simplest way to connect SomatXR or QuantumX
modules to the Data Recorder is via FireWire. Connect
cable 1-KAB272-x to any of the Data Recorder's connec
tions and the other end to connection X102 of the near
est measurement module.
Then keep threading: connection X102 to X101 of the
second measurement module, etc. Remember the maxi
mum current of 1.5 A. As a rule, you must introduce a
voltage supply again after 3 modules
.
You can also con
nect measurement modules at the second FireWire con
nection X102 of the CX22B-R.
In the configuration shown below, the module supply volt
age is looped through via FireWire (max. 1.5 A via
FireWire). The power consumption of a module is ex
plained in the data sheet
.
You can connect up to 12 modules to the CX22B‒R Data
Recorder via FireWire, with a supply feed required for at
least every 3rd module. The supply voltages must have
approximately the same voltage level. The general
SomatXR MX modules operating manual contains more
detailed data on this
.
Notice
If the modules are used in a vehicle, we recommend to
supply the connected MX modules via a separate battery
or a UPS (e.g. UPX002). The integrated UPS of the
CX22B-R will not power the connected modules. In case
of voltage drops the measurement will stop if the MX
modules are not buffered.
